Night Optics Falcon 6x Gen 3 Gated Long-Range Night Vision Binocular - Manual (Page 78)

2-43
NOTE
•
The objective lens cap, compass, or the sacrificial
window will fit onto the end of the objective lens
with the LIF in place. On some systems when the
LIF is installed, the objective lens cap or the
sacrificial window will not fit on the objective lens
as completely as on other systems.
• The LIF must be used at all times unless directed
by the unit commander to remove the LIF, based
upon his/her assessment of the laser threat in the
theater of operations. Use of this filter will result in
a slight reduction in system gain.
(7) Install the objective lens cap or the sacrificial window
over the LIF.
2-12 INSTALLATION OF IR SPOT/FLOOD LENS
Press the IR spot/flood lens over the IR source window until it is
tight against the goggles. Refer to Figure 2-12.
